If it is facial skin allergy, under normal circumstances, medication is mainly based on the specific damage caused by the patient's allergy. Under normal circumstances, if the allergy in this part is only an inflammatory erythema, tacrolimus ointment or styrene-butadiene hydroxy acid cream can be used externally to diminish inflammation. Of course, if itching is obvious, you can also apply some compound camphor ointment or paeonol ointment to relieve itching. At the same time, oral antihistamines, such as loratadine or ebastine, need to be combined. However, if facial skin allergy causes obvious erosion, it is necessary to use physiological saline or 3% boric acid solution for cold compress at this time.
